WEST LAFAYETTE, Ind. -- A 20-year-old Purdue University student was killed in his dorm room early Wednesday and his roommate is in custody, school officials said.
Varun Manish Chheda, a senior majoring in data science, was found dead in his room at McCutcheon Hall, a residence hall on the school's campus in West Lafayette, Indiana, after the suspect called 911 to report the incident at 12:44 a.m. local time, Purdue University Chief of Police Lesley Weite said at a news conference Wednesday.
The suspect, 22-year-old Gji Min Sha, a junior majoring in cyber security, is in custody on a charge of murder, Weite said. He is an international student from Korea, she said.
No other roommates lived with the victim and suspect, Weite said.
"I believe this was unprovoked and senseless," she said.
"Our hearts go out to the victim and his family and friends," she added. "I can't even imagine what his family is going through."
A university spokesperson said, with the suspect apprehended, "there is no threat to the community."
"This is as tragic an event as we can imagine happening on our campus and our hearts and thoughts go out to all of those affected by this terrible event," Purdue University President Mitch Daniels said in a statement Wednesday morning. "We do not have all the details yet. Our Purdue University Police Department is conducting a thorough investigation of this incident so that we all may learn more about what transpired."
